The hot air generated by the hot air generating device 6 is fed to the grains from the machine wall 1b on the rear side of the machine body 1.
An exhaust duct 7 is provided on the outer surface, which leads to the space a formed below the floor plate portion 21 of the grain bin 2. An exhaust fan 70 is connected to the exhaust duct 7, and the suction pressure of the exhaust fan 70 causes the drying air to cross the inner cavity of the grain bin 2 from the air guide duct 24 and be exhausted to the outside of the machine, thereby forming a suction type.

Further, 8 is a hopper for feeding the grains to the elevator 5 when the grains to be dried are put into the grain tank 2, and is a hopper on one side of the machine wall in the left and right direction of the machine body 1. 11, an opening 80 is provided at a position corresponding to the space a formed below the floor plate portion 21 of the grain tank 2 described above.
By providing a drawer and a pusher freely to the opening 80, it is installed to serve as a lid for the opening 80, and as shown in FIGS. 2 and 3, the opening can be opened by pulling it out. By opening 80, it becomes ready to receive grains.
At the lower edge of the opening 80 connected to the proximal edge of the hopper 8, an inclined shelf is installed so as to be inclined downward toward the carrying-out conveyor 3 provided at the bottom of the internal cavity of the machine body 1. The upper edge of the plate 31 is connected so that the grains fed from the hopper 8 flow through the flow plate 31 to the conveyor 3 for carrying out, and are fed to the elevator 5 by the conveyor 3. .

Reference numeral 9 denotes a grain take-out port provided in the peripheral wall of the grain tank 2, which is located in the sloping floor plate portion 21 forming the funnel-shaped bottom of the grain tank 2 in the peripheral wall. The hopper 8 is installed at a location corresponding to the opening 80, and is closed by a lid 90 formed in the shape of a door that can be opened and closed. By arranging the outlet 9 on the peripheral wall of the grain tank 2 and disposing it inside the hopper 8 for loading grain installed on the machine wall 11, a conveyor 3
